1 . Until recently, several lines of evidence — from fossils genetics, and archaeology — suggested that humans first moved from Africa into Eurasia (the land of Europe and Asia) about 60,000 years ago, quickly replacing other early human species, such as Neanderthals and Denisovans, that they may have met along the way.
However, a series of recent discoveries, including 100,000-year-old human teeth found in a cave in China, have clouded this straightforward statement. And the latest find, a prehistoric jawbone at the Misliya Cave in Israel dating back to nearly 200,000 years ago, which is almost twice as old as any Homo sapiens (智人) remains discovered outside Africa, where our species was thought to have originated from, has added new and unexpected twist.
The find suggests that there were multiple waves of migration across Europe and Asia and could also mean that modern humans in the Middle East were interacting, and possibly mating, with other human species for tens of thousands of years. “Misliya breaks the mould (模式) of existing assumptions of the timing of the first known Homo sapiens in these regions,” said Chris Stringer, head of human origins at the Natural History Museum in London. “It’s important in removing long-lasting-constraint (限制) on our thinking.”
Prof. Hershkovitz, who led the work at Tel Aviv University said, “What Misliya tells us is that modern humans left Africa not 100,000 years ago, but 200,000 years ago. This is revolution in the way we understand the evolution of our own species.” He also added that the record now indicates that humans probably travelled beyond the African continent whenever the climate allowed it. “I don’t believe there was one big departure from Africa,” he said. “I think that throughout hundreds of thousands of years humans were coming in and out of Africa all the time.”
The discovery means that modern humans were potentially meeting and interacting during a longer period with other ancient human groups, providing more opportunity for cultural and biological exchanges. It also raises interesting questions about the fate of the earliest modern human pioneers. Genetic data from modern-day populations around the world strongly suggest that everyone outside Africa can trace their ancestors back to a group that left around 60,000 years ago. So, the inhabitants of the Misliya Cave are probably not the ancestors of anyone alive today, and scientists can only guess why their branch of the family tree came to an end.

All the calculations were led to the same conclusion only if you put the sun there did the movements of the other planets make sense. The problem arises because astronomers had noticed that some planets appeared brighter at time and less bright at others. Between 1510 and 1514 Copernicus worked on his new theory, gradual improving it until it was complete. Then he showed it privately for his friends. They encouraged him to publish his ideas, and Copernicus was cautious. He published it as he lay died in 1543. Her theory is now the basis on what all the ideas of universe are built

4 . Lost cities that have been found
The White City
In 2015, a team of explorers to Honduras in search of"the Lost City of the Monke God"led to the discovery of the White City. They found the ruins in the Mosquitia region of the Central American country which is known for poisonous snakes, vicious jaguars and deadly insects. It is believed that local people hid here when the Spanish conquerors(征服者) occupied their homeland in the16th century.
Canopus and Heracleion
Modern researchers were teased by the ancient writings about the Egyptian cities Canopus and Heracleion- where Queen Cleopatra often visited. But the cities weren’t found until 1992, when a search in Alexandria waters found that the two cities had been flooded for centuries. Artifacts(史前器物) showed that the cities once highly developed as a trade network, which helped researchers piece together more about the last queen of Egypt.
Machu Picchu
A Yale professor discovered "the Lost City in the Clouds"in 1911. A combination of palaces, plazas, temples and homes, Machu Picchu displays the Inca Empire at the height of its rule. The city, which was abandoned in the 16th century for unknown reasons,was hidden by the local people from the Spanish conquerors for centuries keeping it so well preserved.
Troy
The ancient city of Troy in homer's The Iliad was considered a fictional setting for his characters to run wild. But in 1871, explorations in northwestern Turkey exposed nine ancient cities layered (层叠) on top of each other, the earliest dating back to about 5,000 years before. It was later determined that the sixth or seventh layer contained the lost city of Troy and that it was actually destroyed by an earthquake, not a wooden horse.
1. Why did people hide in the White City in the 16th century?| A．To survive the war |
| B．To search for a lost city. |
| C．To protect their country. |
| D．To avoid dangerous animals |
| A．The White City |
| B．Canopus and Heracleion |
| C．Machu Picchu |
| D．Troy |
| A．It was built by Homer. |
| B．It consisted of nine cities |
| C．It had a history of 5,000 years |
| D．It was ruined by a natural disaster. |
